Hola Manuel.

Quizás la solución más fácil es que aproveches las ventajas del ECMP (equal
cost multi path), esto se hace de form automática cuando tienes dos rutas
con la misma métrica, la misma distancia administrativa y la misma red de

Si corres un IGP, esto puede llegar a hacerse sin intervención tuya al ver
caminos perfectamente iguales al mismo destino. Sino, vas a tener que poner
algunas rutas estáticas (con tracking e ip sla) para que se vuelvan nulas
al no responder el otro lado.

Claro está, esto no sirve para interfaces bridgeadas, solo ruteadas.

Cualquier cosa me contactas por unicast y te paso algunos ejemplos.

>>>> This pressure has resulted in a marked increase in the use of

>>>> This has three important implications for Internet technology
